Everything should be fine, you might just have the wrong version installed.
There’s a version for the Genesis Framework, and then there’s the Standalone version that is the Full Site Editor version.
You probably have the Genesis version installed. If you want to use the Patterns, you can install the “Full Site Editor” version (it’s the latest version of the theme).
However, if you did want to use the Genesis Framework, then you would need to install the “Collections Plugin” and use the “Layouts” option (it works similar to Patterns).
Personally, I would just use the latest version with the Patterns.
Let me know if that works.
